There are many factors at play however assuming you have a d16y7 block and wire in vtec you should have similar power to a d16z6 or d16y8.
You will also need to wire in vtec-e, vtec and use the correct ecu or have a custom tuned ecu.
If you are only going to swap only the head with out wiring in vtec into the correct ecu you will not see a big power gain.
